Abstract

The photophysical characteristics of a PAMAM-type dendron that utilizes a 4-ethoxy-1,8-naphthalimide donor and 4-piperidine-1,8-naphthalimide acceptor in nine organic solvents of different polarities were investigated using absorption and fluorescent spectroscopy. The 1,8-naphthalimide acceptor can be indirectly excited by the donor 1,8-naphthalimide at 372 nm whereby the only emission observed is that due to the acceptor at 517 nm; no acceptor emission at 435 nm was observed. The efficiency of energy transfer was ∼98%.
