  Tuning the solid-state emission of small push-pull dipolar dyes to the far-red through variation of the electron-acceptor group

  摘要：

  Series of solid-state emitters based on the D-pi-A dipolar structure and featuring various electron-donor and electron-acceptor groups were designed, and their spectroscopic properties studied. From weak emission in dilute solutions, intense emissions in aggregated state (ATE) and in the crystalline state were obtained. Analysis in light of crystal structures obtained by X-ray diffraction revealed specific crystal packing and presence of long chain of emitting aggregates. This simple molecular engineering around the D-pi-A dipolar structure provides easy access to a wide range of effective solid-state emitters allowing modulation of emission wavelengths up to the near infrared (lambda(em) reaching 735 and 768 nm for compound 2f and 3f bearing the strongest electron-withdrawing group).

  Two new indan-1,3-dione and carbazole-based (IDC) compounds with single and four covalently connected chromophores were synthesized and their optical properties were investigated in solutions and in solid films with the emphasis on the interchromophore interactions. Because of molecule twisting, opening transitions to n pi* states, IDC chromophores experience ultrafast excited state relaxation with the time constant of about 2 ps in solutions and several times slower solid films. Chromophore connection into quadruplicate molecules only weakly influence their spectroscopic properties in solutions, however prevents H-type aggregate formation and concomitant spectral changes in solid films.
