Claims23
An organic solid-state laser containing a compound represented by the following formula (1):
- wherein:
- G1 and G2 each independently represent a hydrogen atom or a substituent;
- FL1 and FL2 each independently represent a linking group represented by the following formula (2) or formula (3):
- wherein R1 to R6, R11 to R18 and Z1 to Z6 each independently represent a hydrogen atom or a substituent, R1 and R2, R5 and R6, R12 and R13, and R16 and R17 may be bonded together to form a ring, and each * represents a bonding site;
- BT represents a linking group represented by the following formula (4) or formula (5):
- wherein Y1 represents an oxygen atom, a sulfur atom or N-T1, Y2 represents an oxygen atom, a sulfur atom or N-T2, Y3 represents an oxygen atom, a sulfur atom or N-T3, Q1 represents a nitrogen atom or C—X1, Q2 represents a nitrogen atom or C—X2, Q3 represents a nitrogen atom or C—X3, Q4 represents a nitrogen atom or C—X4, T1 to T3 each independently represent a substituted or unsubstituted alkyl group, X1 to X4 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group or a halogen atom, or X1 and X2 may be bonded together to form a ring, and each * represents a bonding site;
- n1, n2 and m each independently represent an integer of from 1 to 5;
- rightmost n2 may be 0;
- and when m is an integer of from 2 to 5 and rightmost n2 is 0, then n1 may be 0;
- when m is two or more, then two or more instances of BT may be the same or different, two or more instances of FL2 may be the same or different, and two or more instances of n2 may be the same or different;
- when n1 is two or more, then two or more instances of FL1 may be the same or different;
- and
- when n2 is two or more, then two or more instances of FL2 may be the same or different.
