Rhodanine-Bridged Core-Expanded Naphthalene Diimide Derivatives for n-Type Semiconductors
Organic Materials, 2020 The core expansion of naphthalene diimides (NDIs) is an effective strategy to modulate frontier molecular orbital energy levels and improve device performances.

Crystals, 2022 Quaternary phosphonium salts are popular candidates used in many chemical transformations and synthetic chemistry, notably in catalysis. We have examined the single crystals of two bulky phosphonium compounds, tetra([1,1′-biphenyl]-4-yl) phosphonium ...

Intrinsic Universality in Self-Assembly [PDF]
, 2009 We show that the Tile Assembly Model exhibits a strong notion of universality where the goal is to give a single tile assembly system that simulates the behavior of any other tile assembly system.

Nature Communications, 2017 Block copolymers that form nanodomains and are used in nanolithography usually do not form nanopatterns with multiple shapes. Here the authors report a block copolymer that allows for UV- induced cleavage of one arm and demonstrate the transformation of ...

Noncooperative algorithms in self-assembly [PDF]
, 2014 We show the first non-trivial positive algorithmic results (i.e. programs whose output is larger than their size), in a model of self-assembly that has so far resisted many attempts of formal analysis or programming: the planar non-cooperative variant of

A versatile platform for precise synthesis of asymmetric molecular brush in one shot
Nature Communications, 2017 Producing well-defined polymer compositions and structures facilitates their use in many different applications. Here the authors show the synthesis of well-defined asymmetric double-brushes by a one-pot concurrent atom transfer radical polymerization ...

Electrostatic theory of viral self-assembly: a toy model [PDF]
Physica A 387, 3059 (2008), 2006 Viruses self-assemble from identical capsid proteins and their genome consisting, for example, of a long single stranded (ss) RNA. For a big class of T = 3 viruses capsid proteins have long positive N-terminal tails. We explore the role played by the Coulomb interaction between the brush of positive N-terminal tails rooted at the inner surface of the ...

Self-Assembly of Infinite Structures [PDF]
, 2009 We review some recent results related to the self-assembly of infinite structures in the Tile Assembly Model. These results include impossibility results, as well as novel tile assembly systems in which shapes and patterns that represent various notions ...

Shape-induced anisotropy in antidot arrays from self-assembled templates [PDF]
, 2005 Using self-assembly of polystyrene spheres, well-ordered templates have been prepared on glass and silicon substrates. Strong guiding of self-assembly is obtained on photolithographically structured silicon substrates.

Design Rules for Self-Assembly of 2D Nanocrystal/Metal-Organic Framework Superstructures. [PDF]
, 2018 We demonstrate the guiding principles behind simple two dimensional self-assembly of MOF nanoparticles (NPs) and oleic acid capped iron oxide (Fe3 O4 ) NCs into a uniform two-dimensional bi-layered superstructure.
