1. A fluorescent compound represented by the following general formula (1): wherein R1 to R4 each independently represent a substituent selected from a linear, branched or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms, alkoxy group having 1 to 20 carbon atoms, aryloxy group having 6 to 20 carbon atoms, halogen atom, hydrogen atom, amino group, cyano group, amine-containing group represented by the following general formula (2), and siloxane-containing group represented by the following general formula (3); or the carbon atoms at the ortho position of the nitrogen atom bonded to X directly bond to each other to form a carbazole ring structure, resulting in that R1 is not present; with the proviso that when an amine-containing group represented by the general formula (2) as the substituent is not included, at least one of R1 to R4 is a siloxane-containing group represented by the following general formula (3), and that when an amine-containing group represented by the following general formula (2) as the substituent is included, at least one of R1 to R6 is a siloxane-containing group represented by the following general formula (3); each of X may be identical or different, represents a single bond, or a linear, branched or cyclic divalent hydrocarbon group having 1 to 20 carbon atoms, and some of the carbon atoms may be substituted with a heteroatom; and n is an integer of 0 to 5: wherein R5 and R6 each independently represent a substituent selected from a linear, branched or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms, alkoxy group having 1 to 20 carbon atoms, aryloxy group having 6 to 20 carbon atoms, halogen atom, hydrogen atom, amino group, and siloxane-containing group represented by the following general formula (3); and m is 0 or 1;
Sx-A- (3) wherein Sx represents a linear, branched or cyclic organosiloxanyl group having 2 to 10 silicon atoms and a monovalent hydrocarbon group having 1 to 20 carbon atoms bonded to at least one of the silicon atoms; and A represents a single bond, or a linear, branched or cyclic divalent hydrocarbon group having 1 to 20 carbon atoms which may contain at least one of —O—, —S— or —NR0—, or a combination thereof, with the proviso that heteroatoms of oxygen, sulfur and nitrogen are not adjacent to each other except the case where A is a cyclic divalent hydrocarbon group, and R0 is a monovalent hydrocarbon group having 1 to 20 carbon atoms. |
