The absorptionspectra and emission spectra of 4-substituted2H-1-benzo/napthopyran-2-ones 3a-1 have been determined in THF and DMSO. The substituent at the 4-position of the 2H-benzo/napthopyran-2-one, establishes a compact conjugation pathway in which the pyran-2-one nucleus can act as an acceptor ring.
已经确定了在THF和DMSO中4-取代的2 H -1-苯并/萘并吡喃-2-酮3a-1的吸收光谱和发射光谱。在2 H-苯并/萘并吡喃-2-酮的4位上的取代基建立了紧密的共轭途径,其中吡喃-2-一核可充当受体环。
