Abstract

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.

2. The compound described in claim 1 , wherein R 3 s in Formula (1-1) and Formula (1-2) are the same group selected from the group consisting of alkyl having 1 to 20 carbons, phenyl, furyl and thienyl.

3. The compound described in claim 2 , wherein R 3 s in Formula (1-1) and Formula (1-2) are the same group selected from the group consisting of alkyl having 6 to 12 carbons.

4. The compound described in claim 1 , wherein in Formula (1-1) and Formula (1-2), each R 3 is independently alkyl having 1 to 20 carbons or aryl, wherein at least one hydrogen in the alkyl may be replaced with fluorine, and at least one hydrogen on a ring of the aryl may be replaced with at least one selected from the group consisting of fluorine and alkyl having 1 to 10 carbons.

5. A method for producing a compound represented by Formula (1):

wherein, in Formula (1), each X is independently sulfur, or selenium; m is 0 or 1; each n existing at two positions is independently 0 or 1; R 1 -R 3 are each independently hydrogen, fluorine, alkyl having 1 to 20 carbons, aryl, pyridyl, furyl, thienyl or thiazolyl, wherein at least one hydrogen in the alkyl may be replaced with fluorine, and at least one hydrogen on a ring of the aryl, pyridyl, furyl, thienyl and thiazolyl may be replaced with at least one selected from the group consisting of fluorine and alkyl having 1 to 10 carbons;
