1. A composition of materials comprising a first compound, wherein the first compound has a formula:

wherein G¹is selected from the group consisting of dibenzofuran, dibenzothiophene, dibenzoselenophene, and fluorene;

wherein L¹, L²and L³are each independently selected from the group consisting of direct bond, phenyl, biphenyl, terphenyl, pyridine, pyrimidine, and combinations thereof;

wherein G⁴is selected from the group consisting of phenyl, biphenyl, terphenyl, naphthalene, phenanthrene, pyridine, pyrimidine, pyrazine, quinoline, isoquinoline, phenanthroline, and combinations thereof;

wherein G², G³, and G⁵are each independently selected from the group consisting of phenyl, biphenyl, terphenyl, fluorene, naphthalene, phenanthrene, pyridine, pyrimidine, pyrazine, quinoline, isoquinoline, phenanthroline, aza-fluorene, and combinations thereof;

wherein G², G³, G⁴, and G⁵are each optionally further substituted with one or more unfused substituents selected from the group consisting of deuterium, alkyl, alkoxyl, cycloalkyl, cycloalkoxyl, halogen, nitro, nitrile, silyl, phenyl, biphenyl, terphenyl, pyridine, and combinations thereof;

wherein m is an integer from 0 to 7,

wherein n is an integer from 0 to 4;

wherein, when m or n is larger than 1, each G⁴or G⁵can be same or different;

wherein, when n is 0, m is equal to or greater than 1 and each G⁴is selected from the group consisting of phenyl and biphenyl;

wherein when n is equal to or greater than 1, L¹is not a direct bond;

wherein m+n is at least 1;

if L¹is phenyl, then at least one of the following is true: (i) n is 0, (ii) n is 1 and G⁵is not biphenyl, or (iii) m+n is at least 2, and

wherein at least one of the following is true:
