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, 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.)
提供了一种能产生 SHG 信号但抑制 TPF 信号产生的化合物。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,该化合物是式 (1) 的偶氮苯衍生物或其盐。(R1和R2独立地代表具有6-12个碳原子的烷基,R3至R18独立地代表选自氢、卤素、烷基、烷氧基、芳基、氨基、羟基、硝基和氰基的取代基,R5和R6、R9和R10、R13和R14以及R17和R18可结合在一起并形成具有5-7个碳原子的环结构。X 代表-N+R19R20R21、磺酰基、羧基或-OR 基。这里,R19、R20 和 R21 独立地代表具有 1-5 个碳原子的直链或支链烷基,-OR 代表以烷氧基为末端的单价聚氧化亚烷基(a 是 0 或 1,b 是 0 或 1,n 是 1-10 的整数)。
