Brain-derived neurotrophic factor (BDNF) is identified as a potent neuroprotective and neuroregenerative agent for many neurological diseases. Regrettably, its delivery to the brain hampered by poor serum stability rapid clearance. Here, novel nanoformulation reported composed of bio-compatible polymer, poly(ethylene glycol)-b-poly(L-glutamic acid) (PEG-PLE), that hosts BDNF molecule in nanoscale complex, termed here Nano-BDNF. Upon simple mixture, Nano-BDNF spontaneously forms uniform...
The design of molecular rotors that can rotate at ultrahigh speeds is important for the development artificial machines. Based on theoretical calculations, we demonstrate two kinds carbon nano-rings, i.e. [n]cycloparaphenylenes ([n]CPP) and cyclo[18]carbon (C18), form an ultrafast ring-in-ring nano-rotor through π-π interaction. As a high-symmetry low-barrier rotator, rotational frequency C18 in [11]CPP close to THz regime. At low temperatures, motion [11]CPP:C18 system purely rotational....

Unstable tri-metallofullerenes Ln 3 @C 80 are greatly stabilized in their cationic form. The stability of @C80 + originates from a three-center two-electron metal–metal bond that compensates for the Coulomb repulsion between metal ions.
Superhalogen is a special class of atomic clusters whose electron affinity larger than that chlorine atom, which has the largest in periodic table elements. In this paper, we report fabrication new magnetic superhalogen by encapsulating two rare-earth metal atoms into Ih symmetrical C80 fullerene.

Density functional theory calculations reveal...
The photoluminescence of lanthanide ions inside fullerenes is usually very weak due to the quenching effect fullerene cage. In case Er@C82, near-infrared emission from Er3+ ion completely quenched by C82 It remains challenging turn on Er@C82 and other monometallofullerenes. this work, we adopt a covalent modification strategy alter electronic structure cage for sensitizing in metallofullerenes Er@C2n (2n = 72, 76, 82). After with trifluoromethyl, phenyl, or dichlorophenyl groups, erbium...
Abstract In this work, we theoretically designed a new class of fullerene derivatives, metallofullerene heterodimers, through cross dimerization monomers Li@C 60 , Y@C 82 and Y 2 @C 80 . The molecular structures, electronic linear nonlinear optical properties the heterodimers were studied by using density functional theory calculations. We found that two cages are connected relatively weak carbon‐carbon single bond. Inter‐cage electron transfer takes place in because different accepting...
Full control of the regioselectivity in functionalization fullerenes is important for production fullerene derivatives with desirable properties. Cycloaddition reactions C60 usually take place at hexagon-hexagon ring junction, i.e. [6,6] bond cage, whereas [5,6] generally unreactive. The activation toward Diels-Alder difficult because its longer length than bond. In this study, we computationally demonstrate that can be efficiently activated by encapsulation a divalent metal atom such as Ca...
Single-walled carbon nanotubes (SWCNTs) have evoked great interest for various luminescent applications, but the large emission heterogeneity resulting from structural complexity of samples seriously restricts their further development. Herein we theoretically explore electronic structures and optical properties phenine (pNTs), which are typical SWCNT derivatives with determined molecular that been synthesized recently (Z. Sun, K. Ikemoto, T. M. Fukunaga, Koretsune, R. Arita, S. Sato H....
