The Universe

There are many approaches to deal with vagueness and ambiguity including soft sets and rough sets. Feng et al. initiated the concept of possible hybridization of soft sets and rough sets. They introduced the concept of soft rough sets, in which parameterized subsets of a universe set serve as the building blocks for lower and upper approximations of a subset. Topological notions play a vital role in rough sets and soft rough sets. So, the basic objectives of the current work are as follows: first, we find answers to some very important questions, such as how to determine the probability that a subset of the universe is definable. Some more similar questions are answered in rough sets and their extensions. Secondly, we enhance soft rough sets from topological perspective and introduce topological soft rough sets. We explore some of their properties to improve existing techniques. A comparison has been made with some existing studies to show that accuracy measure of proposed technique shows an improvement. Proposed technique has been employed in decision-making problem for diagnosing heart failure. For this two algorithms have been given.

This thesis describes the synthesis of a novel family of 4,4─difluoro─4─bora─3a─4a─diaza─s─indacenes for material and education applications (BODIPYs). This thesis also presents the exploration of their optical and electrochemical properties, as well as potential for application in dye─sensitised solar cells, and synthetic laboratories. Chapter 1 gives an overview of the photophysical of chromophores of large organic electronics. BODIPYs are introduced as suitable building blocks for such applications, and synthetic approaches for extending the conjugation of these fluorophores are presented. Chapter 2 gives an overview the development of an engaging senior undergraduate laboratory course based on BODIPY that reinforces traditionally important technical skills and explore property─directed synthesis & research. Chapter 3 describes the use of the redox robust ferrocene as electron donor in the synthesis of ferrocene─BODIPY dyes for DSSC applications. Chapter 4 explores the effects of confined intramolecular π─stacking on the physicochemical properties of π─π BODIPY dimers in cyclophane architectures through the synthesis of a novel cyclophane consisting of BODIPY and anthracene moieties.

Molecular Building Blocks

The inability to synthesize hierarchical structures with independently tailored nanoscale and mesoscale features limits the discovery of next-generation multifunctional materials. We present a programmable molecular self-assembly strategy to craft nanostructured materials with a variety of phase-in-phase hierarchical morphologies. The compositionally anisotropic building blocks employed in the assembly process are formed by multi-component graft block copolymers (GBCPs) containing sequence-defined side chains. The judicious design of various structural parameters in the GBCPs enables broadly tunable compositions, morphologies, and lattice parameters across the nanoscale and mesoscale in the assembled structures. Our strategy introduces new design principles for the efficient creation of complex hierarchical structures and provides a facile synthetic platform to access nanomaterials with multiple precisely integrated functionalities.
