      abstract     = {Tunability of functional properties in a continuous manner
                      is desired but challenging to accomplish for organic
                      solid-state materials. Herein, we describe a method for
                      tuning optoelectronic properties of solid-state aggregates
                      with narrow absorption bands. First, we systematically shift
                      the absorption maxima of highly dipolar merocyanine dyes in
                      solution by chemical alterations of their chromophore cores.
                      This leaves their solid-state packing arrangements
                      unchanged, affording similar J- and H-coupled aggregate
                      absorption bands at different wavelengths. Next, mixing
                      these isostructural dyes leads to a spectral fine-tuning of
                      the mixed layers, which could be characterized as
                      crystalline organic solid solutions and utilized in
                      narrowband color-selective organic photodiodes. Finally, we
                      devise a semiempirical model, which explains the observed
                      spectral tuning in terms of the molecular exciton theory.
                      Thus, we demonstrate narrowband absorbing solid-state
                      aggregates spanning the wavelength range of 437–760 nm,
                      whose absorption can be fine-tuned over $40\%$ of the
                      visible light range.},
