Single-walled carbon nanotubes (SWCNTs) have the potential to revolutionize nanoscale electronics and power sources; however, their low purity and high separation cost limit their use in practical applications. Here we present a supramolecular chemistry-based one-pot, less expensive, scalable, and highly efficient separation of a solubilizer/adsorbent-free pure semiconducting SWCNT (sc-SWCNT) using flavin/isoalloxazine analogues with different substituents. On the basis of both experimental and computational simulations (DFT study), we have revealed the molecular requirements of the solubilizers as well as provided a possible mechanism for such a highly efficient selective sc-SWCNT separation. The present sorting method is very simple (one-pot) and gives a promising sc-SWCNT separation methodology. Thus, the study provides insight for the molecular design of an sc-SWCNT solubilizer with a high (n,m)-chiral selectivity, which benefits many areas including semiconducting nanoelectronics, thermoelectric, bio and energy materials, and devices using solubilizer-free very pure sc-SWCNTs.

The microwave-enhanced synthesis of 10-substituted isoalloxazines is achieved rapidly (~4 min) and in good yield (>80-95%) via the cyclocondensation of 2-substituted aminoanilines with alloxan or N-methylalloxan monohydrate in the presence of acidic alumi

At room temperature in aqueous solution, the visible absorption peak (S1) of the title isoalloxazine (3) gave a well resolved, three-band fine structure which is believed to appear only in apolar solvents or in enzymatic hydrophobic pockets where isoallox

A biscoenzime which has within a molecular structure both flavin and thiazolium ion was synthesized.In the presence of the biscoenzyme and hexadecyltrimethylammonium bromide (CTAB) micelle, aldehydes were efficiently converted to carboxylic acids and the acyloin condensation products were scarcely detected. Thus, the biscoenzyme serves as an interesting model system for pyruvate dehydrogenase.
