摘要 Structural properties of nucleobase underlie their ultrafast excited-state dynamics and low fluorescence quantum yields, which cause effectively nonradiative decay process and render them like sunscreens. Thus, eight guanine analogs[N-2-（2＇-nitrobenzoyl）-guanine, N-2-（3＇-nitrohenzoyl）-guanine, N-2-（4＇-nitrobenzoyl）-guanine, N-2-（2＇-hydroxybenzoyl）-guanine, N-2-（4＇-methoxylbenzoyl）-guanine, N-2-（4＇-chloricbenzoyl）-guanine, N-2-（4＇- me- thylicbenzoyl）-guanine and N-2-（3＇,5＇-dinitrobenzoyl）-guanine] with different substituted benzoyls, except N-2-（4＇-chloricbenzoyl）-guanine, were newly synthesized. In contrast with guanine, they exhibit wider ultraviolet absorbent range, higher molar extinction coefficient and lower fluorescence intensity.
