Provided are a compound that generates an SHG signal but has suppressed generation of a TPF signal. Also provided is a cell examination method using the same. A compound for generating a second harmonic of light, the compound being an azobenzene derivative of formula (1), or a salt thereof. (R1 and R2 independently represent alkyl groups having 6-12 carbon atoms, and R3 to R18 independently represent substituents selected from hydrogen, halogens, alkyl groups, alkoxy groups, aryl groups, amino groups, hydroxyl groups, nitro groups, and cyano groups, but R5 and R6, R9 and R10, R13 and R14, and R17 and R18 may combine together and form a ring structure having 5-7 carbon atoms. X represents —N+R19R20R21, a sulfonyl group, a carboxyl group, or an —OR group. Here, R19, R20, and R21 independently represent straight-chain or branched alkyl groups having 1-5 carbon atoms, and —OR represents a monovalent polyalkylene oxide group terminated by an alkoxy group. a is 0 or 1, b is 0 or 1, and n is an integer of 1-10.)
提供了一种产生SHG信号但抑制TPF信号生成的化合物。还提供了一种使用该化合物的细胞检查方法。一种用于产生光的二次谐波的化合物,该化合物是具有式(1)的偶氮苯衍生物,或其盐。(R1和R2独立表示具有6-12个碳原子的烷基基团,R3至R18独立表示从氢、卤素、烷基基团、烷氧基团、芳基、氨基、羟基、硝基和氰基中选择的取代基,但R5和R6、R9和R10、R13和R14以及R17和R18可以结合在一起形成具有5-7个碳原子的环结构。X表示—N+R19R20R21、磺酰基、羧基或—OR基团。这里,R19、R20和R21独立表示具有1-5个碳原子的直链或支链烷基基团,—OR表示由烷氧基终止的一价多聚氧化烷基氧基团。a为0或1,b为0或1,n为1-10的整数。
