Synthesis of Lewis adduct-based indenophenanthridine and study of its tunable optoelectronic properties toward an amine sensor

Abstract

A nitrogen-boron based Lewis adduct was synthesized from indenophenanthridine derivatives, exhibiting a greatly extended emission wavelength (100 nm) and a Stokes shift up to 270 nm. The photophysical properties were evaluated in the solid and solution state and under low-temperature conditions. The synthesized boronated adduct 2a was found to exhibit radiometric fluorescence variations toward volatile aliphatic amines with real sample applications.
