TL;DR: Using a back-thinned CCD as the detector, the sensitivity for spectral detection in both the short and long wavelength regions is greatly improved compared with that of an optical detection system that uses a conventional photodetector.

TL;DR: The structural variations were found to affect the fluorescence quantum yields significantly, which are up to 0.84, and the structure-property relationships were studied by extensive UV-vis and fluorescence spectroscopic measurements, cyclic voltammetry (CV), and theoretical calculations as well as X-ray crystallographic analyses.

TL;DR: The number of thiophene units was found to affect the extent of π-conjugation, the resulting HOMO-LUMO gaps, and fluorescence efficiency, and the crystal structures of 5 and 9 were disclosed.

TL;DR: Thienopyrrole-fused compounds 1b and 2b displayed bathochromically shifted intramolecular charge-transfer (CT) bands and low oxidation potentials as compared to indole-fuse analog 3b and showed moderate to good fluorescence quantum yields (Φ(f)) up to 0.73.

TL;DR: Time-resolved photoacoustic measurements and photophysical properties show that the occurrence of fast internal conversion in MBC and MMBC can be explained in terms of the proximity effect, i.e., pseudo Jahn-Teller coupling between energetically close S(1) and S(2) states.
