A compound is represented by Formula (1):
wherein, each X is independently oxygen, sulfur, or selenium; m is 0 or 1; each n is independently 0 or 1; R
1
-R
3
are each independently, for example, hydrogen or alkyl having 1 to 20 carbons;
wherein
(i) in the case of m=0, it is excluded that all of R
1
-R
3
are hydrogen at the same time;
(ii) in the case of m=0, n=0 and in the case that m is 0, one of n is 0 and the other is 1, it is excluded that “both of X are sulfur and all R
3
s are the same atoms or groups at the same time”;
(iii) in the case of m=0, n=1, it is excluded that all R
3
s are the same atoms or groups at the same time, and at least one of R
3
s is hydrogen.
化合物由式(1)表示:其中,每个X独立地为氧、硫或硒;m为0或1;每个n独立地为0或1;R1-R3各自独立地为氢或具有1至20个碳的烷基;其中(i)在m=0的情况下,排除所有R1-R3同时为氢的可能性;(ii)在m=0,n=0的情况下,或在m为0时,其中一个为0,另一个为1的情况下,排除“X均为硫且所有R3同时为相同的原子或基团”的可能性;(iii)在m=0,n=1的情况下,排除所有R3同时为相同的原子或基团的可能性,并且至少有一个R3为氢。
