Functional layer material, light-emitting device, light-emitting substrate and light-emitting apparatus

A functional layer material, comprising a compound centered on an sp3 hybridized carbon atom, wherein

• the compound centered on the sp3 hybridized carbon atom includes a first type of compound, and the first type of compound is selected from any one of structures shown in a following general formula (I):
• wherein values of a, b, m and n are each independently selected from any one of 0, 1, 2, 3 and 4, and at least one of a, b, m and n is not 0;
• A1 and A2 are same or different, and are each independently selected from any one of a substituted or unsubstituted trivalent aryl group, a substituted or unsubstituted fused ring trivalent aryl group, and a substituted or unsubstituted fused ring trivalent heteroaryl group;
• B1 and B2 are same or different, and are each independently selected from any one of a substituted or unsubstituted alkylene group, a substituted or unsubstituted arylene group, and a substituted or unsubstituted heteroarylene group;
• L1, L2, L3 and L4 are same or different, and are each independently selected from any one of a single bond, a substituted or unsubstituted phenylene group, a substituted or unsubstituted biphenylene group, a substituted or unsubstituted terphenylene group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted adamantyl group, and a substituted or unsubstituted heteroarylene group;
• and
• Ar1, Ar2, Ar3, Ar4, Ar5, Ar6, Ar7 and Ar8 are same or different, and are each independently selected from any one of a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, a substituted of unsubstituted fused ring aryl group and a substituted or unsubstituted fused ring heteroaryl group.
