Abstract:
Hydrogen bonds are formed in the phenol-formaldehyde-ortho-naphthoquinondiazide-water system. In our work quantum-chemical calculations were made using the HF/3-21G ++ theory level and it was found out that phenol-formaldehyde forms three types of hydrogen bonds: between its hydroxyl group and carbonyl group of ortho-naphthoquinondiazide, between its hydroxyl group and water and between its hydroxyl groups intramolecularly forming a "circle-like" structure, and this type of bonds prevails.
Keywords: phenol-formaldehyde, ortho-naphthoquinondiazide, hydrogen bonds, photoresist
