Patent ID: 8350035

Claim:
A method of manufacturing a semiconductor, the method comprising: combining at least one compound of formula I with a substrate: n is 3, or 4, at least one of the R n1 , R n2 , R n3 , and R n4 radicals is fluorine, optionally, at least one further R n1 , R n2 , R n3 , and R n4 radical is a substituent which is selected from Cl and Br, and remaining radicals are each hydrogen, Y 1 is O or NR a , wherein R a is hydrogen or an organyl radical, Y 2 is O or NR b , wherein R b is hydrogen or an organyl radical, Z 1 , Z 2 , Z 3 , and Z 4 are each O, with the proviso that wherein, in the case that Y 1 is NR a , optionally, one of the Z 1 and Z 2 radicals is NR c , wherein the R a and R c radicals together are a bridging group having from 2 to 5 atoms between the flanking bonds, and wherein, in the case that Y 2 is NR b , optionally, one of the Z 3 and Z 4 radicals is NR d , where the R b and R d radicals together are a bridging group having from 2 to 5 atoms between the flanking bonds.
