“…During previous quantification of diamondoids, cyclopentadecane, deuterated n-alkanes or diamondoids were usually used as internal standards (Wingert, 1992;Dahl et al, 1999;Schulz et al, 2001;Wei et al, 2006a;Springer et al, 2010). To simplify, however, relative response factors (RRF) of each diamondoid to the corresponding internal standards were generally assumed to be one.…”

“…Therefore, complex sample preparation procedures are not recommended for the quantification of diamondoids in crude oils, especially adamantanes. The MAI (methyl adamantane index, 1-MA/(1-MA + 2-MA)) and MDI (methyl diamantane index, 4-MD/(4-MD + 1-MD + 3-MD)) are the most commonly used maturity indices for evaluating highly mature crude oils or source rocks (Chen et al, 1996;Schulz et al, 2001;Wei et al, 2006bWei et al, , 2007b (Grice et al, 2000;Schulz et al, 2001;Wei et al, 2007b). These indices are generally calculated from the peak areas of the related compounds obtained from the mass chromatograms of the GC-MS analyses.…”

“…Since adamantane (the simplest diamondoid) was first discovered in petroleum in 1933, more diamondoids have been detected in many crude oils (Bender et al, 1986;Williams et al, 1986;Wingert, 1992;Chen et al, 1996;Dahl et al, 1999;Grice et al, 2000;Azevedo et al, 2008), petroleum products (Wang et al, 2006), coals and sedimentary rocks (Imuta and Ouchi, 1973;Aczel et al, 1979;Schulz et al, 2001;Wei et al, 2006a), and gas condensates (Lin and Wilk, 1995;Stout and Douglas, 2004;Sassen and Post, 2008). Furthermore, some higher diamondoids (more than three diamond cages) have been separated and identified from petroleum (Dahl et al, 2003).…”

“…Therefore, before introducing oil samples into the gas chromatograph, a preparative group separation step is usually employed to eliminate the matrix interference. In such preparation procedures, hexane or pentane eluates are concentrated by evaporation to a small volume prior to sample injection to improve analytical sensitivity (Wingert, 1992;Chen et al, 1996;Grice et al, 2000;Li et al, 2000;Schulz et al, 2001;Zhang et al, 2005). Moreover, the sensitivity of diamondoid analysis can be enhanced by using selective ion monitoring (SIM) mode of GC-MS, such as monitoring m/z 136, 135, 149, 163, 177 and 191 for adamantanes, m/z 188, 187, 201, 215 and 229 for diamantanes, and m/z 240, 239, 253, 267 and 281 for triamantanes (Wingert, 1992;Schulz et al, 2001).…”

“…Therefore, some biomarkers with high resistance to these secondary alterations, such as diamondoid hydrocarbons (Wingert, 1992), triaromatic steroid hydrocarbons (Peters and Moldowan, 1993a;Williams et al, 1986), pregnane and homopregnane (Peters et al, 2005b;Wenger and Isaksen, 2002), were selected for the oil-source correlations. Since diamondoid hydrocarbons are highly resistant to severe thermal alteration and biodegradation after oil expulsion (Wingert, 1992;Grice et al, 2000), they are useful for oil-oil correlation in cases where the oil and bitumen have suffered severe biodegradation or thermal cracking (Schulz et al, 2001). Pregnane and homopregnane are also highly resistant to biodegradation.…”

Diamondoids have been of great interest in recent years due to their role in nanotechnology, drug-delivery and medicine. In this review paper we introduce at first the cage nature of diamondoid molecules (polymantanes, adamantologues), the variety of their crystalline lattice structures, the nature of their structural isomers, their stereoisomers, and their other molecular specificities are presented. The carbon-carbon framework of diamondoids constitutes the fundamental repeating unit in the diamond lattice structure. It is demonstrated that diamondoids are very stable compounds.The unique physicochemical properties of diamondoids due to their exceptional atomic arrangements including their melting points, molar enthalpies, molar entropies, molar heat capacities, vapor pressures and other phase transitions and solubilities data are reported and analyzed.The Lewis acid-catalyzed rearrangement of hydrocarbons to synthesize lower diamondoids is presented and its limitations for the synthesis of higher diamondoids are discussed.The natural occurrence of diamondoids in petroleum fluids and how they come to be present in such fluids is introduced. Field experiences of phase transitions and depositions as well as techniques for separation, detection and measurement of diamondoids from petroleum fluids is presented and discussed..It is demonstrated that due to their six or more linking groups diamondoids have found major applications as templates and as molecular building blocks in polymers synthesis, nanotechnology, drug delivery, drug targeting, DNA directed assembly, DNA-amino acid nanostructure formation and in host-guest chemistry. ________________________________________ (*) E-Mail: mansoori@uic.edu. 2 Molecular Structure of DiamondoidsDiamondoid molecules are cage-like, ultra-stable, saturated hydrocarbons. These molecules are ringed compounds, which have a diamond-like structure consisting of a number of six-member carbon rings fused together (see Figure 1). More explicitly, they consist of repeating units of ten carbon atoms forming a tetra-cyclic cage system [1-3]. They are called "diamondoid" because their carbon-carbon framework constitutes the fundamental repeating unit in the diamond lattice structure. This structure was first determined in 1913 by Bragg and Bragg [4] using X-ray diffraction analysis.The first and simplest member of the diamondoids group, adamantane, is a tricyclic saturated hydrocarbon (tricyclo[3.3.1.1]decane). Adamantane is followed by its polymantane homologues (adamantologues): diamantane, tria-, tetra-, penta-and hexamantane. Figure 1, illustrate the smaller diamondoid molecules, with the general chemical formula C 4n+6 H 4n+12 : adamantane (C 10 H 16 ), diamantane (C 14 H 20 ), and triamantane (C 18 H 24 ),.. These lower adamantologues, each has only one isomer.Depending on the spatial arrangement of the adamantane units, higher polymantanes (n≥4) can have several isomers and non-isomeric equivalents. There are three possible tetramantanes all of which are isomeric. They are depicte...
