Abstract
A silylated anthracene derivative, bis [2-(p-trimethylsilyl) phenylethynyl] anthracene (1), was synthesized by using Sonogashira reaction. Compound 1 showed two absorption maxia (λmax, abs) at 444 and 447 nm, and fluorescence maximum (λmax, em) at 478 nm. Compound 1 had higher melting temperature of 274° C compared to anthracene 210° C presumably due to confinement of π-conjugated system by trimethylsilyl end-capping, ...
