Pyrromethene-boron complex, color conversion composition, color conversion film, light source unit, display, and illumination device

A pyrromethene-boron complex compound with a molecular weight of 1000 or more, represented by the following general formula (1):

• wherein at least two of R1 to R6 in the general formula (1) are groups represented by the following general formula (2):
• wherein, in the general formula (1),
• X is C—R7 or N;
• R1 to R9, other than the groups represented by the following general formula (2) of R1 to R6, each are the same or different, and selected from the group consisting of hydrogen, alkyl, cycloalkyl, heterocyclyl, alkenyl, cycloalkenyl, alkynyl, hydroxy, thiol, alkoxy, alkylthio, aryl ether, aryl thioether, aryl, heteroaryl, halogen, cyano, aldehyde, carbonyl, carboxyl, acyl, ester, amide, carbamoyl, amino, nitro, silyl, siloxanyl, boryl, sulfoxide, sulfonyl, phosphine oxide, and a fused ring formed by adjacent substituents;
• wherein, in the general formula (2),
• L2, each independently, is selected from the group consisting of alkylene, cycloalkylene, arylene, heterocyclyl, and heteroarylene;
• when L2 is alkylene, the carbon atom bound to L1, in the alkylene group, is secondary or tertiary carbon;
• R101, each independently, is selected from the group consisting of cyano, aryl, and cycloalkyl;
• n is each independently an integer of 0 to 5, and m is each independently an integer of 1 to 5;
• each (L2-(R101)n) comprises three or more ring structures;
• and
• L1, each independently, is selected from the group consisting of carbonyl, —C(═O)O—, —C(═O)N<, —S(═O)2—, and —P(═O)<.
