Mori H, Nakazato R, Tachibana H, Shimada T, Ishida T, Ryo M, Hasegawa E, Takagi S. Fluorescence enhancement of benzimidazolium derivative on clay nanosheets by surface-fixation induced emission (S-FIE). Photochem Photobiol Sci 2024; 23:1077-1086.

Abstract
The photophysical behaviors of benzimidazolium derivative [4-(1,3-dimethylbenzimidazol-3-imu-2-yl)-N, N-diphenylaniline (2-(4-(diphenylamino)phenyl)-1,3-dimethyl-1H-benzo[d]imidazol-3-ium)] (BID) in water, organic solvents and on synthetic saponite were investigated. The fluorescence quantum yield (Φf) of BID was 0.91 on the saponite surface under the optimal condition, while that in water was 0.010. Such fluorescence enhancement on the inorganic surface is called "surface-fixation induced emission (S-FIE)". This fluorescence enhancement ratio for BID is significantly high compared to that of conventional S-FIE active dyes. From the values of Φf and the excited lifetime, the non-radiative deactivation rate constant (knr) and radiative deactivation rate constant (kf) of BID on the saponite surface and in water were determined. Results showed that the factors for fluorescence enhancement were both the increase of kf and the decrease of knr on the saponite surface; especially, knr decreased by more than two orders due to the effect of nanosheets.

Abstract
The present paper gives a brief account of the latest advances in understanding of the mechanism and implications of dye adsorption with a special focus on layered silicate surfaces. It has been clearly demonstrated that the controlled adsorption of novel or already well-known dyes has equally great yet unexplored potential. In principle, the well-engineered surface confinement of the molecules may lead to their aggregation, adsorption, or intercalation-induced fluorescence emission even with conventional dyes, which are not considered as luminophores in solutions or in the solid state. We envision the utilization of silicate-based heterogeneous systems to produce novel polymer blended films or structured liquids, as well as to develop a plethora of other photophysical and biomedical applications.

Boosting the fluorescence (FL) intensity for a weak/nonemissive molecule is a challenge. This work describes the improvement of FL intensity for a nonemissive conformationally twisted π-conjugated pyridyl salt. This pyridyl...
