KEYWORDSA novel fluorescent co-polymer with an organoboron quinolate and an E-BODIPY (BODIPY: 4,4-difluoro-4-bora-3a-4a-diaza-s-indacene) moiety was synthesized with the aim of producing a donor-acceptor polymeric system where the organoboron quinolate acts as the donor and the E-BODIPY moiety is the acceptor. The polymer has three prominent absorption bands: 264 nm (corresponding to the organoboron quinolate), 397 nm (corresponding to the organoboron quinolate and BODIPY) and 516 nm (corresponding to the E-BODIPY moiety). Excitation of the organoboron quinolate at 264 nm resulted in emission at 525 nm, giving a 261 nm Stokes shift. Energy transfer from the donor (organoboron quinolate) unit to the acceptor (BODIPY) explains the origin of this large Stokes shift.

A triphenylcyclopropenium salt paired with hydroxytris(pentafluorophenyl)borate counter ion was synthesized as an initiator for cationic polymerization and its activity was compared with triphenylcyclopropenium hexafluoroantimonate. Triphenylcyclopropenium hydroxytris (pentafluorophenyl)borate exhibits excellent activity as a room temperature thermal initiator for epoxide polymerization under solvent free conditions, due to excellent solubility in epoxy resins.Epoxy Initiator Plasticizer Borate salts Polymerization Infrared spectroscopy
