Conjugated Dendrimer: Characterization of a New Class of Organic Materials

Abstract

This paper reports ground and excited states calculations of dendrimer by a methodology based on INDO/S, including electronic correlation CI. The results reveal the existence of different electronic patterns for the different generations of this molecule. The results indicate that this class of dendrimers has a peculiar behavior on dipole moment of the different families. These results are consistent with recent experimental data supporting the importance of this state for the mechanism of the interaction of dendrimer. The mechanism of relaxation of dendrimer is supported by the absorption spectra simulation and the conclusion comes by analysis of main transitions presents on different generations of this class of molecules.

From Sensors to Molecular Logic: A Journey

“…It seems probable that these molecules will continue to serve fields as diverse as medical diagnostics, nanoscience, and information processing in the coming years [123][124][125]. These molecules can also be inserted into tiny spaces of critical human importance, while still maintaining their functionality.…”

Electrical Signature of Graphene and Dendrimer Nanoantennas

“…The systems presented in Figure 1 have the similar methods and they are new point-of-view and applications when compared with models presented before. [48][49][50][51][52] …”

“…6 In the case of optical nanoantenna, the radiation resistance using optical circuit elements. 7 In the same way, dendrimers have been investigated with several applications 8 as: (a) Investigation of stability of encapsulated PPI dendrimer with 64 functional groups (up to G5-generation) and the influence of oxygen on the clusters stability demonstrating that huge amount of oxidation enhances the cluster stability; 9 (b) Synthesis of organic and inorganic hybrid dendrons showing good solubility in organic solvents and the possibility of self-assembled layers of low generation dendrons and amphiphilic feature; 10 (c) Carbosiloxane dendrimers were utilized to produce organic nanocrystals and the result was regular shape and size up to 100 nm presenting direct manifestation of optical properties and crystal size; 11 (d) Dendrimer nanostars as a tool for understanding of dendrimer [12][13][14] and dendrimer/nanotube generation; 15 16 (e) Chromatic polynomials for certain polyphenylene dendrimers; 17 (f) Organic conjugated Dendrimer; 18 (g) and the theoretical investigation of Hosoya index utilized to design new dendrimers possibilities and topologies [19][20][21] and others. [22][23][24] In the otherwise, the development of antennas made of graphene is, at the moment, an open possibility and state-of-art technology has been developed to achieve this goal.…”

Molecular Electronics Devices: A Short Review

“…A semiconducting as well resistive behaves presenting rectification as electrical feature. Also, the nonlinear signature happens with asymmetry in the current-voltage curves and bi-directional operation regions, in forward and reverse bias for donor-large heterogeneous bridgeacceptor 40 (Fig. 3 (top panel)).…”
