“…[1] As to aerosol particle formation from gaseous molecules, carbon disulfide (CS2) was recently studied upon exposure to NZ laser light [2][3][4][5], and it was found that the sedimental aerosol particle was neither carbon monosulfide polymer nor carbon disulfide polymer, but an amorphous mixture of sulfur polymer and carbon polymer hitherto unknown [6]. Based on these results, we can expect to synthesize a variety of new solid materials from gaseous mixtures of organic molecules.…”

Upon exposure to N2 laser light, a gaseous mixture of methyl acrylate (MA) and carbon disulfide (CS2) deposited sedimental aerosol particles on a glass plate placed at the bottom of the irradiation cell, together with a thin fil m on the surface of an optical quartz window. Aerosol particles deposited from the gaseous mixture was spherical with a mean diameter of X0.3 ,um. The mean diameter and the product yield deposited from a gaseous mixture of MA (50 Ton) and CS2 (30 Ton) gradually increased with increasing irradiation time of N2 laser light. IR spectrum of the sedimental aerosol particles showed the bands characteristic of poly(methyl acrylate), indicating that MA is polymerized into the aerosol particles produced from CS2.

“…1). On the other hand, a gaseous mixture of Fe(CO) 5 (1.1 Torr) and CS 2 (2.0 Torr) produced spherical sedimentary aerosol particles with a mean diameter of 0.28 mm, although pure CS 2 vapor at a pressure of 2 Torr did not produce any deposits [10][11][12][13][14]. The morphological change of the deposits from the gaseous mixture clearly showed that CS 2 molecules were incorporated into the photochemical reactions of Fe(CO) 5 .…”

From a gaseous mixture of Fe(CO) 5 and CS 2 , sedimentary aerosol particles involving organometal compounds were produced under UV light irradiation at 313 nm. Chemical composition of the sedimentary aerosol particles was controlled by a magnetic field and by post-exposure with UV light. By applying a magnetic field up to 5 T, photochemical reactivity of Fe(CO) 5 molecules was promoted and the amount of chemical species originating from Fe(CO) 5 increased with increasing magnetic field. By irradiating UV light upon the deposited particles, solid-state photochemical reactions took place in the particles, and CO groups bonded to Fe atom were effectively evolved from the sedimentary aerosol particles. These methods can be utilized to modify chemical composition of the metal-containing sedimentary particles. q

“…A polymer similar to Bridgman's carbon disulfide [1] was obtained through irradiations resonant with the 280-390 nm band allowing formation and polymerization of excited CS 2 molecule, CS, S 2 and CS species. [2][3][4][5][6][7][8] A (CS) x polymer containing S-centered radicals and >C S, >C C<, S 2 C CS 2 , -C-(C S)-S-, -S-(C S)-S-and C-S-S-C configurations was prepared by laser irradiations into the 230-190 nm band, which allowed dissociation of CS 2 into CS and S (e.g., ref. [9,10] ) and chemical vapor deposition of (CS) x polymer [11] through polymerization of the transient CS radical.…”

Summary: Laser irradiation at 193 nm of gaseous mixtures of carbon disulfide and ethene induces copolymerization of both compounds and affords chemical vapor deposition of conjugated nano‐chained C/S/H polymer, with contributions from C2H4 and CS2 almost unaffected by very different initial ratio of both educts. The polymer structure is interpreted on the basis of X‐ray photoelectron and FTIR spectra as consisting of >CS, >CC<, CH2CH2, (CC)SnC4−n, C(CS)S, S(CS)S and CSSC configurations, whose extent is dependent on the irradiation conditions.Typical TEM image of the solid copolymer obtained by laser‐induced copolymerization of carbon disulfide and ethene.magnified imageTypical TEM image of the solid copolymer obtained by laser‐induced copolymerization of carbon disulfide and ethene.
