as minor product; B-1: weakly arched, saber-shaped crystal aggregates with monoclinic single crystals strung together in the form of a ladder (P2,/a, a = 31.3, 6 = 4.04, c = 6.05 A, fl = 90.3 "), about half as thick as they are wide, with convex arched narrow faces, from diethyl ether by layering wi
The fluorescence decay times of excimers of anthracene, perylene, pyrene aud 1-methylnapbthalene have been studied in a rigid cyclohexane matrix of low temperatures. From the observed long decay times of the excimer fluorescence, it has been concluded that the excimer fluorescence is due to the ele
The novel 2,6-donor-acceptor-substituted anthracene, of the anthracene 7 in solution yields the syn and anti headto-tail dimers exclusively. A synergistic electronic effect namely 6-methoxy-2-anthracene carboxylic acid ( ), was synthesized. The emission of this compound exhibits between the donor an
