Here, we investigated the fluorescence of two π-extended [n]helicenes with different helical lengths n, named [7] and [9], under high pressures in a diamond anvil cell. The experimental results showed that compound [9], with a longer helical length, exhibited a more sensitive fluorescence response than [7] in both crystalline and solvated states upon compression. Theoretical calculations reveal that π–π overlapping at their helices in these molecular springs provides an additional contribution to their fluorescence properties under compression when the overlap becomes sufficiently strong. Our results provide insights into structure–property relationships of helical molecules under high-pressure conditions and verify the potential of helicenes as molecular springs for future applications in molecular machines. 000630612 536__ $$0G:(DE-HGF)POF4-6G3$$a6G3 - PETRA III (DESY) (POF4-6G3)$$cPOF4-6G3$$fPOF IV$$x0 000630612 536__ $$0G:(DE-H253)I-20220099$$aFS-Proposal: I-20220099 (I-20220099)$$cI-20220099$$x1 000630612 588__ $$aDataset connected to CrossRef, Journals: bib-pubdb1.desy.de 000630612 693__ $$0EXP:(DE-H253)P-P02.2-20150101$$1EXP:(DE-H253)PETRAIII-20150101$$6EXP:(DE-H253)P-P02.2-20150101$$aPETRA III$$fPETRA Beamline P02.2$$x0 000630612 7001_ $$0P:(DE-HGF)0$$aJu, Cheng-Wei$$b1 000630612 7001_ $$0P:(DE-HGF)0$$aLiu, Zonghang$$b2 000630612 7001_ $$0P:(DE-H253)PIP1027478$$aLi, Hailong$$b3 000630612 7001_ $$0P:(DE-H253)PIP1091697$$aKarina, Aigerim$$b4 000630612 7001_ $$0P:(DE-H253)PIP1100202$$aEklund, Tobias$$b5 000630612 7001_ $$0P:(DE-HGF)0$$aZheng, Wenhao$$b6 000630612 7001_ $$0P:(DE-H253)PIP1024001$$aAmann-Winkel, Katrin$$b7 000630612 7001_ $$0P:(DE-H253)PIP1092881$$aCai, Weizhao$$b8 000630612 7001_ $$0P:(DE-HGF)0$$aWagner, Manfred$$b9 000630612 7001_ $$0P:(DE-HGF)0$$aQiu, Zijie$$b10$$eCorresponding author 000630612 7001_ $$0P:(DE-HGF)0$$aWeil, Tanja$$b11$$eCorresponding author 000630612 7001_ $$0P:(DE-HGF)0$$aMüllen, Klaus$$b12$$eCorresponding author 000630612 773__ $$0PERI:(DE-600)2011836-3$$a10.1002/anie.202500923$$gVol. 64, no. 21, p. e202500923$$n21$$pe202500923$$tAngewandte Chemie / International edition$$v64$$x1433-7851$$y2025 000630612 8564_ $$uhttps://bib-pubdb1.desy.de/record/630612/files/Angew%20Chem%20Int%20Ed%20-%202025%20-%20Liang%20-%20Fluorescence%20of%20Helical%20Molecular%20Springs%20Under%20High%20Pressure.pdf$$yOpenAccess 000630612 8564_ $$uhttps://bib-pubdb1.desy.de/record/630612/files/Angew%20Chem%20Int%20Ed%20-%202025%20-%20Liang%20-%20Fluorescence%20of%20Helical%20Molecular%20Springs%20Under%20High%20Pressure.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000630612 909CO $$ooai:bib-pubdb1.desy.de:630612$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000630612 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1099788$$aExternal Institute$$b0$$kExtern 000630612 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1027478$$aExternal Institute$$b3$$kExtern 000630612 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1091697$$aExternal Institute$$b4$$kExtern 000630612 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1100202$$aExternal Institute$$b5$$kExtern 000630612 9101_ $$0I:(DE-588)1043621512$$6P:(DE-H253)PIP1100202$$aEuropean XFEL$$b5$$kXFEL.EU 000630612 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1024001$$aExternal Institute$$b7$$kExtern 000630612 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1092881$$aExternal Institute$$b8$$kExtern 000630612 9131_ $$0G:(DE-HGF)POF4-6G3$$1G:(DE-HGF)POF4-6G0$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vPETRA III (DESY)$$x0 000630612 9141_ $$y2025 000630612 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-16 000630612 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000630612 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)9915$$2StatID$$aIF >= 15$$bANGEW CHEM INT EDIT : 2022$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)3001$$2StatID$$aDEAL Wiley$$d2024-12-16$$wger 000630612 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)1210$$2StatID$$aDBCoverage$$bIndex Chemicus$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000630612 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)1200$$2StatID$$aDBCoverage$$bChemical Reactions$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANGEW CHEM INT EDIT : 2022$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-16 000630612 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2024-12-16$$wger 000630612 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-16 000630612 9201_ $$0I:(DE-H253)HAS-User-20120731$$kDOOR ; HAS-User$$lDOOR-User$$x0 000630612 980__ $$ajournal 000630612 980__ $$aVDB 000630612 980__ $$aUNRESTRICTED 000630612 980__ $$aI:(DE-H253)HAS-User-20120731 000630612 9801_ $$aFullTexts
