1. A compound having formula C{Ph(R1)i(OR)j}2{Ph(R3)m(OR4)n}{Ph(R5)o(OR6)p}, wherein Ph represents a benzene ring, R1, R3 and R5 independently are C1-C18 alkyl or C4-C18 heteroalkyl; R2, R4 and R6 independently are C1-C18 alkyl or C4-C18 heteroalkyl, i, j, m, n, o and p independently are zero, one or two,
provided that (a) at least one of i and j is not zero, or (b) at least one of m and n and at least one of o and p are not zero; that, when j is one and i, m, n, o and p are zero, then R2 is not C9-C11 alkyl; and that, when n and p are one and i, j, m, and o are zero, R4 and R6 are not C9-C11 alkyl. |
