1. Quinolines by Three-Component Reaction: Synthesis and Photophysical Studies
The synthesis of five quinolines 8-octyloxy-4-[4-(octyloxy)phenyl]quinoline and 6-alkoxy- 2-(4-alkoxyphenyl)-4-[(4-octyloxy)aryl]quinolines are described by three-component coupling reaction mediated by Lewis acid FeCl3 and Yb(OTf)3. 4-n-octyloxybenzaldehyde, anisaldehyde, 4-n-octyloxyaniline p-anisidine, and 1-ethynyl-4-heptyloxybenzene, 1-ethynyl-4-octylox

2. Síntese e caracterização de novos polímeros líquido-cristalinos de cadeia lateral derivados do heterociclo 2-isoxazolínico 3,5-dissubstituído
This thesis presents the synthesis and characterization of new polymer liquid crystal materials based on heterocycle 2-isoxazoline 3,5-disubstituted. We studied the inversion effects of groups linked in position 3 and 5 in 2-isoxazoline in the mesogenic group attached by side chain polymer liquid crystal and the influence in liquid crystals properties. The m

3. Synthesis and mesomorphic properties of side chain liquid-crystalline biphenyl-phenyl polyacrylates
A síntese e a caracterização de dois cristais líquidos poliacrilatos, de cadeia lateral contendo o sistema bifenil-fenila como unidade central são descritos. A cadeia terminal é derivada da L-isoleucina. Em cada caso, o espaçador undecila foi utilizado para conectar o grupo mesogênico e a cadeia polimérica. Ambos os polímeros apresentaram mesofase

4. Chiral liquid-crystalline polyacrilates from (S)-(-)-2-methyl-1-butanol: Synthesis, mesomorphic properties and light scattering
A síntese e o comportamento mesomórfico de dois poliacrilatos quirais líquido cristalinos com cadeia lateral derivados do (S)-(-)-2-metil-1-butanol são descritos. Estes novos poliacrilatos quirais mostram dependência das temperaturas de transição de fase com a massa molar e o comprimento do espaçador. O poliacrilato contendo quatro unidades metilêni

5. Unidirectional rotary motion in a liquid crystalline environment: Color tuning by a molecular motor
Life could not exist without motion induced by a variety of molecular motors. The construction of artificial motors by chemical synthesis, which can power motions that lead to macroscopic detectable effects in a system, is a major endeavor in contemporary science. To move toward this goal, a host–guest system, composed of a nematic liquid crystal film dope

6. Self-assembling biomaterials: Liquid crystal phases of cholesteryl oligo(l-lactic acid) and their interactions with cells
We report here on the synthesis and characterization of a series of self-assembling biomaterials with molecular features designed to interact with cells and scaffolds for tissue regeneration. The molecules of these materials contain cholesteryl moieties, which have universal affinity for cell membranes, and short chains of lactic acid, a common component of

7. Molecular devices: Caroviologens as an approach to molecular wires—synthesis and incorporation into vesicle membranes
Molecular wires, which would allow electron flow to take place between different components, are important elements in the design of molecular devices. An approach to such species would be molecules possessing an electron-conducting conjugated chain, terminal electroactive polar groups, and a length sufficient to span a lipid membrane. To this end, bispyridi
