ABSTRACT:
A new class of silicon compounds having a high percentage of silicon atoms bonded to three other silicon atoms has been synthesized. These materials denominated polysilynes form smooth amorphous films which have quite useful properties. For example, photooxidation produces a refractive index change from 1.70 to 1.45. Similarly, photooxidation also produces a substantial change in solubility. Thus the materials are useful for the fabrication of optical and electronic devices.
