An object is to provide a semiconductor material and coating having high solubility in solvents and having advantageous filling property, high heat resistance, and/or high etching resistance. Another object is to provide a method for manufacturing a semiconductor using the semiconductor material. Still another object is to provide a novel compound. Provided are: a semiconductor material consisting of a specific aromatic hydrocarbon ring derivative; methods for manufacturing a coating and a semiconductor using the semiconductor material; and a compound consisting of a specific aromatic hydrocarbon ring derivative.

Original glycodendrimers emanating from propargylated hexaphenylbenzene cores and containing up to 54 peripheral sugar ligands have been synthesized by Cu(I)-catalyzed [1,3]-dipolar cycloadditions using both convergent and divergent approaches.

A highly congested hexameric subphthalocyanine array was synthesized by axial chlorine-to-phenoxy substitution of a hexakis(4-hydroxyphenyl)benzene based subphthalocyanine, and photoinduced symmetry-breaking charge separation was demonstrated in polar solvent. The Royal Society of Chemistry 2011.
Hydroxyphenylbenzene derivatives as glass forming molecules for high resolution photoresists
Ober, Christopher K.,De Silva, Anuja
experimental part, p. 1903 - 1910 (2009/09/24)
This paper presents a fundamental study to relate molecular architecture to the amorphous properties of hydroxyphenylbenzene molecular glass derivatives. These studies demonstrates that the branched hydroxyphenylbenzene derivatives can form stable molecular glasses despite the π-π interactions present. Through this research, design concepts to stabilize the amorphous nature and to increase the glass transition temperature (Tg) based on asymmetric molecular structures, bulky substituents, conformation states and molecular size are explored. An understanding of such behavior is important for the development of hydroxyphenylbenzene derivatives as potential molecular photoresists for patterning below 50 nm. This research has helped to identify potential candidates to be evaluated as positive-tone photoresists for lithographic applications for extreme ultraviolet (EUV, λ = 13.4 nm) lithography. The first reported sub-30 nm feature sizes for hydroxyphenylbenzene derivatives were demonstrated with high Tg materials. The Royal Society of Chemistry.
Self-assembly of a radially functionalized hexagonal molecule: Hexakis(4-hydroxyphenyl)benzene

Two different porous hydrogen-bonded networks are formed by self- assembly of the radially substituted host 1. In the network of type A, formed by 1 · 4Et2O, all OH groups of 1 are involved in hydrogen bonding, and the molecular sheets are stacked without translation to generate extended channels that accommodate the Et2O molecules. Four OH groups of 1 are involved in the type B network of 1 · 4DMF, and lateral translation of the sheets in an ABAB sequence generates large chambers, each of which contains four DMF molecules.
