All-Carbon Polymers (Polyfullerenes) from Photochemical Reactions of Fullerene Clusters in Room-Temperature Solvent Mixtures

Light-Scattering Characterization of Fullerene-Containing Poly(alkyl methacrylate)s in THF

“…14. The chain density (F) of the aggregate in its hydrodynamic volume estimated on the basis of F ) M w /(4/3π〈R h 〉 3 N A ) is as low as 2 × 10 -4 g/cm 3 . Therefore, the shell made of the stretched polymer chains should be very soft and compressible.…”

Towards better understanding of C60organosols

“…One of the specific features of fullerenes is their ability to form aggregates. [8][9][10][11][12][13][14] While in low-polar aromatic solvents, fullerenes are well solvated and relatively well dissolved, 14,15 in water they generate hydrosols and suspensions. 5,11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] In highly polar organic solvents, the molecular solubility of fullerenes is negligible, 14,15 but they readily form colloidal solutions.…”

“…5,11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] In highly polar organic solvents, the molecular solubility of fullerenes is negligible, 14,15 but they readily form colloidal solutions. [9][10][11][12][13][14][31][32][33][34][35] The state of fullerenes, either molecular or colloidal, in the so-called 'good' or 'strong' solvents, such as CS 2 , toluene, and benzene, is still a matter of discussion. 8,10,11,14,[36][37][38][39][40] Some authors believe that in such a case, aggregates appear only as a result of sonication.…”

“…8,38,41 In contrast, in polar or 'poor' organic solvents, the formation of colloidal species is undoubtedly proven. 9,[11][12][13][14][31][32][33][34][35] Typical examples are aggregates in N-methylpyrrolidin-2-one-acetonitrile mixed solvent, 3 toluene (benzene) mixtures with acetonitrile, 9,12,36 N-methylpyrrolidin-2-one 11,33 and other polar solvents, 13 DMSO, 31 acetonitrile, acetone, ethanol, methanol, and other polar solvents. 32,35,42 Though the stability and coagulation of aqueous C 60 colloids via electrolytes has been examined in full, 14,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][43][44][45][46][47][48][49] the corresponding research for organosols is absent to the best of the authors knowledge.…”

Conformation and Interactions of Polystyrene and Fullerenes in Dilute to Semidilute Solutions

“…C 60 can be found as a single molecule in solution, and can cluster into colloidal particles on the order of 100's nm or crystallise, depending on solvent quality. 16 We select toluene as a good solvent for PS and also comparatively good for C 60 , which is miscible up to 0.32 wt%. 17 We evaluate two main aspects of polymer/fullerene solutions: the effect of C 60 on the conformation of PS chains, and the effect of PS on miscibility and aggregation of C 60 .…”
